Trillió

Trillió is the Hungarian name for the number 10^18. It is part of the long-scale naming system used in Hungarian to name large integers. In this system the sequence around trillió is millió (10^6), milliárd (10^9), billió (10^12), billiárd (10^15), trillió (10^18), and trilliárd (10^21).

In contemporary Hungarian, trillió is mainly used in technical, scientific, or mathematical contexts and in formal writing. In everyday speech, Hungarians typically describe such large values with approximate expressions or scientific notation rather than spelling out the full number.

Etymology and context: trillió belongs to the Hungarian long-scale nomenclature for large numbers. It corresponds to 10^18. In comparison to English usage on the short scale, 10^18 would commonly be called a quintillion, illustrating how naming systems differ between languages.
